This appears to be Soviet war game footage. This was pretty typical of the Soviet Union -- they staged massive war games -- and would be broadcast within the USSR and Warsaw Pact as a propaganda device to showcase the skills of its combined arms forces. If I had to guess, I would guess that it was filmed while being broadcast on Soviet television.
The vaguely "Arab" looking troops we see in the armored vehicles are very likely Central Asian soldiers who, by the mid-1980s, were being conscripted at comparatively higher rates than European Soviets, who had brought draft evasion to a high art.
Indicators: 1) at 0:10, a PT-76 amphibious tank emerges from the sea, and before it passes the camera we see a Soviet naval infantry flag painted on the side of the hull;
2) at 2:11, we see transport helicopters crossing right to left and observers in the foreground -- the officers are wearing service hats and uniforms rather than helmets and field gear, indicating they are not in combat;
3) the troops at 2:57
are Soviet paratroops;
4) the artillery at 3:37
and the anti-aircraft artillery at 3:57
is not emplaced or dug-in and protected by sandbags, as they would be in combat;
5) at 6:17, the troops come running at the camera, firing, but make no effort to conceal themselves or avoid return fire, as they would in combat;
6) the armored vehicles at 8:48
are Soviet BST-008 self-propelled artillery guns;
7) at 9:02
we see what appears to be a group of 9K52 Luna rockets on 9T29 transporters;
8) at 9:09
we see a group of Soviet staff officers receiving a map briefing (real or imagined);
9) at 11:11
we see SA-3 Goa anti-aircraft surface-to-air missiles;
10) at 14:20
we see Soviet naval infantry again, landing on what is obviously uncontested terrain.
